PAD FOR TRUSSES.

Application filed September A29, 1926. Serial No. 138,506.

My invention relates to pads for trusses for the treatment of ruptures and similar troubles. y Y

The principal object of this invention 1s to provide a pad having a central raised head or bearing portion, and a surrounding friction surface, whereby the pad is arranged to remain in suitable and comfortable adjustment, and also to provide superior' features of 'treatment for the ailments for which such pads are designed. Y

vFurther objects of the invention will appear from the following detailed description thereof.

In the drawings:

Figure l is a front View of a truss pad` constructed in accordance with this invention.

Figure 2 is a Side elevation of said pad.

Figure 3 is a cross-section of said pad.

The numeral l indicates a pad constructed ofsoft or sponge rubber or other'similal` material. The pad l is provided with an annular undercut groove 2 which forms a central head 3. The undercut is` so made as to provide around the head 3 a thin feather edge 4 which is of areadily pliable and resilient nature. The main body of the pad Y1 surrounding the head 3 is provided with a 4roughened or non-skid surface 5. The surface 5 is formed bymean's of reticulated grooves, as shown in the drawings, or in any other suitable manner. i

The pad l is secured in the usual manner to a base plate 6 whereby in turn it issecured to a truss supporting member 7.

From the foregoing description, the na,

ture and value of the present invention will be apparent to those skilled n the artto which. the same appertains.

Av truss pad constructed as above descrlbed provides, as Y will be seen, ahead 3V which is adapted to rest in or against the point of rupture thus amply sustaining the same and moreV iirmly than in the case of the ordinary simple trusspad heretofore in use. Furthermore, by rea# son of the outward tapering of the head'to the feather edge 4, the head is maintained more eectively in the rupture opening thanV y will serve to maintain the pad effectively in position. In other Words, the feather edge is susceptible of a vibratory or fluttering motion'during the breathing or other movements of the patient which tends-to and doesk create a suction which forces inwardly the central portion of they head of the pad. It is thus possible to maintain a pad of the present construction in position with a much lighter and iieXible truss spring than is the case with a rigid or uniformlyv solid pad even where such pad is provided with ahead, thus contributing greatly to the comfort and well being of thepatient.

Having thus fully described my invention, what I yclaim as new and desire to secure by Letters Patent is:

l. A pad for trusses, comprising a body, a resilient head over the middle portion of said body, said head tapering outwardly to a thin resilient surrounding edge.

2. A 'pad for trusses, comprising a body, a resilient head over the middle portion of said body, said head tapering outwardly to athin resilient surrounding edge, and a nonskid surface on said body surrounding said head.
